gh-99418: Make urllib.parse.urlparse enforce that a scheme must begin with an alphabetical ASCII character. (#99421)
Prevent urllib.parse.urlparse from accepting schemes that don't begin with an alphabetical ASCII character.
RFC 3986 defines a scheme like this: `scheme = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )`
RFC 2234 defines an ALPHA like this: `ALPHA = %x41-5A / %x61-7A`
The WHATWG URL spec defines a scheme like this:
`"A URL-scheme string must be one ASCII alpha, followed by zero or more of ASCII alphanumeric, U+002B (+), U+002D (-), and U+002E (.)."`
